TRAY.

Application filed March .7, 1916'. Serial No. 82,643.

the use of cardboard, strawboard and similar homogeneous material, because when bent such material has a tendency to break or crack and thus weaken the finally constructed article along its bent edges, and to resume its original form; to insure an excessively tough and smooth frame or side Wall; to facilitate the assemblage and engagement of the constituent parts of the tray; and to attain these ends in an inexpensive structure.

To the above ends essentially my invention consists in such parts and combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification, Figures 1 and 2 are front and edge views respectively of a length of the material intended to form the base strip or lining strip, Figs. 3 and 4:, similar views respectively of a length of the frame winding strip, Fig. 5, a side elevation of a partially completed tray, Fig. 6, an enlarged section on line 66 of Fig. 5, Fig. 7 an enlarged plan view of the floor blank, Fig. 8, an enlarged section of the complete tray, Fig. 9, a bottom plan View of an auxiliary floor blank, Fig. 10, a section corresponding to Fig. 8 of a modified form of tray, and FigJll, an enlarged view of a portion of the structure shown in Fig. 8.

Like reference characters indicate like parts throughout the views.

In constructing the frame portion of my tray a foundation or lining piece A, comprising a paper strip a having a dry adhesive coating a of cement, mucilage, glue or the like, upon one face, is wrapped once around a rectangular form of block with the coating exposed. The major portion of the coated surface is next moistened, and upon this moistened surface is coiled a piece B, somewhat narrower than the piece A, comprising a paper strip 7) and a coating 7) consisting of a moist adhesive.

in width of the pieces A and B results in a portion of the former, identified as 0, extending below the body of the frame thus constructed forming a flap with its dry coating 64 exposed, as shown in Figs. 5 and 6.

In the drawings the spaces between the windings, and the thicknesses of the coatings are exaggerated for the purposes of illustration. The frame thus constructed is very tightly wound, giving an unusually tough and compact shell or body weakened by no transverse joint in its side, nor any fracture or seam in its corners, which would occur if a cardboard construction were used.

The bottom of the tray consists of a blank I) conforming in dimensions and contour with the bottom of the shell formed by the piece B, against whose lower edge the blank abuts. The blank may be of cardboard or other desired material as no joints or bends are necessitated therein. It is attached to the body by moistening the coating a on the flap c, which is inturned, and pressing the blank and flap together. The tray thus constructed is shown in Fig. 8. The described tray is easily assembled and constructed, and at small cost.

In cases where extremely heavy articles are sought to be supported in the tray, this type lends itself to the following reinforcement, illustrated in Figs. 9 and 10, wherein I I is a blank of cardboard or other material of a size and contour to fit within the walls of the tray and rest upon the upper face of the flap 0. Upon the lower face of this blank at its central portion is a circular layer of moist adhesive 6 that engages the adjacent face of the blank D. After the frame has been coiled the adhesive therein renders the body somewhat damp and it is found advantageous at this stage of the construction to apply heat and compress the coils in any convenient manner, although this treatment is not imperative.

What I claim is:

1. In a tray, the combination of a frame comprising a series of coils, a lining strip of greater width than the width of the coils and comprising a portion engaging the innermost coil and an inwardly directed flap portion, and a base engaging the flap portion and the coils.

2. In a tray, the combination of a frame comprising a series of compact coils and an adhesive coating between the coils, a lining strip of greater width than the Widthofthe innermost coil and attached to the same, and

coils and attached to the face of the innermost coil provided With an inturned flap portion, and a base engaging tion and the edges of the coils.

3. In a tray, the combination of a frame comprising a series of coils, a lining strip of greater Width than the Width of'the coils and comprising a portion engaging the face of the innermost coil, and an inwardly directed flap portion, an adhesive coating on the flap portion, and a base engaging the coating on the flap portion and bearing against the edges of said coils.

4. In a tray, the combination of a frame comprising a series of coils and an adhesive coating between the coils, a lining strip of greater Width than the Width of the coils and comprising a body portion covering the Copies of this patent may be obtained for the flap por a flapportion provided ith a dry adhesive face,. and a base engaging the flap and the adjacent edges of the coils.

'5. A tray comprising a body portion formed of a multiplicity of coils comprising a frame and a lining Wound upon each other and closely' adhered together, the lining being of greater Width than the outer portion of the tray and forming a'flap, a'bottom engaging the bottom edges of the coilsof the body of the tray and secured to said flap, and an interior reinforcement Within said lining and supported on said flap and secured to the bottom.

In testimony whereof I have afiixed my signature.
